A secret spec Garrett GT-series turbo and a Full Race Motorsports custom race header were scavenged from the Jotech race inventory. The rest of the turbo system includes a Precision FMIC, a TiAL blow-off valve with boost control falling to the tag team duo of a TiAL 46mm wastegate and a GReddy PRofec B boost controller.
The engine needed to be detuned to run on gasoline. The high boost button was set to 27 psi and low boost was dialed in at 12 psi. Kenny started the M4 programming with a map from his racecar. "The big difference was converting from methanol, which burns cooler and therefore takes more volume to make power, to gasoline. Spool-up time for the turbo was also a concern because the turbo's behavior with the two different fuels was night and day. I am really happy with how it came out; we tuned the car in 15 passes." On Jotech's Dynojet the B18C topped out at 643.2 whp and 399.2 lb-ft of torque. We have a dyno chart that encompasses the final four passes and it testifies that the engine was eating up the boost as output jumped 260 whp from the first pull (run 12) to the final pass.
Being a Honda drag racer Kenny knows a thing or two about the weaknesses in the Honda driveline. Changing axles after every pass used to be a fact of life but pushing the envelope has led to the development of heavy-duty driveline parts that make the Honda driveline significantly more reliable. These leading edge components have trickled down into the street market.
Jason's Integra is running a set of Driveshaft Shop Stage V axles. Taking its cues from a Tilton twin-disc Cerametallic clutch, a Quaife differential puts the twist on the new-age axles. Kenny also went inside the Type-R transmission and shot-peened, cryo treated and REM polished some of the key components. All the bases have been covered and it should be interesting to see how long these pieces stand up to over 640 whp.
The Integra has the right kind of footwork for the street. Jason went with TEIN Type-Flex coil-overs. The Type-Flex are the most economical coil-overs that also allow for the use of the TEIN EDFC system. EDFC stands for Electronic Damping Force Controller and the system is basically cockpit remote control for coil-overs. The driver can adjust the damping force of the front and rear shocks separately from the easy-to-install 1/4-DIN controller. The EDFC has a memory function that allows the driver to program a baseline setting, which can be used for everyday street driving. When conditions merit a more aggressive setup the user can re-tune the coil-overs on the fly and later return to the baseline setting at the push of a button.
Stopping power has been addressed with trick Powerslot rotors, Project Mu pads and stainless brake lines working in accordance with the OE calipers. The Acura's rolling stock is made up of sinister-looking blacked-out 15-inch Nippon Racing five-spoke wheels that scream urban warrior and Nitto drag radials.
Since Jason plans to flex this brute's muscles to their fullest, Brink Racecraft of Dallas, Texas installed a six-point roll cage. This is a serious street car and it will be interesting to see the silver and black attack drop the big boost throughout the Big D.

Footwork consists of TEIN Type-Flex coil-overs upgraded with the TEIN EDFC system, which empowers the driver by allowing damping adjustments to the front and rear shocks separately from the easy-to-install 1/4-DIN controller. The EDFC has a memory function that allows the driver to program a baseline setting that he can deviate from when conditions warrant a more aggressive setup.

The 1995 Integra was on its way to becoming a parts car when Jason Jarmon shelled out $1500 for it. Talk about hurting, the car was a non-VTEC LS backed by an automatic transmission. Jason added a Type-R front end conversion, two-tone paint, Jotech race engine and a Type-R tranny to revive the ailing Acura
